Instructor: Cliff Mass TAs: Conor McNicholas Eduardo Mazza Atmospheric Sciences 101 Instructor: Cliff Mass TAs: Conor McNicholas Eduardo Mazza

Goals of class Become knowledgeable observers of the atmosphere Learn how to interpret satellite and radar imagery, as well as weather maps Acquire basic understanding of key atmospheric phenomena Use atmospheric phenomena to understand basic physical principles and laws Basic introduction to climate change and global warming. Become good weather consumers. Learn about best weather web sites, best weather apps, know what is hype and what is real.
